M2 TC+Timer--Temperature control with day/night timer
In this mode, you can set two different temperature settings with two time periods set during 24 hours. Time 1 ~Time 2 ~ Time 1 is a cycle, 24 hours.
For example, set Time 1=8:00, Start Temperature TC 1=25?, Stop Temperature TC 1=28?; Time 2=18:00, Start Temperature TC 2 =28?, Stop Temperature TC 2 =32?.
From 8:00 to 18:00, the heater will start heating when temperature<25? and stop heating when temperature= 28?, when temperature drops below 25? again, the heater will start to work again;
From 18:00 to 8:00 the next morning, the heater will start heating when temperature <28? and stop heating when temperature= 32?, when temperature drops below 28? again, the heater will start to work again.

M1 TC mode -- Temperature control only
Set start temperature and stop temperature, this thermostat plug outlet will work in heating or cooling mode as programmed.
For example, set start temperature=20?, stop temeprature=25?, the heater will start heating when temperature < 20? and stop heating when temperature = 25?, when the temperature drops below 20?, the heater will start to work again.

M3 Timer mode
With ON/OFF time setting per day, you can program your devices to turn on/off regularly.
For example, set Time 1 ON=8:00, Time 2 OFF=18:00, the device will be turned on from 8:00 to 18:00 and turned off from 18:00 to 8:00, then repeat every 24 hours.

Temperature Calibration
Press and hold "M", the screen will display 0.0, press "+" or "-" to adjust the temperature difference. Range: -9.9?~9.9?.

Switch between Celsius and Fahrenheit
Press and hold "OK" for 3s to switch between Celsius and Fahrenheit.

Reset Function
Press and hold the back button for 3s to restore factory settings. Note: Temperature calibration value will not be reset.
